WOVEN-WIRE FABRIC FOR BED-BOTTOMS.

SPECIFICATION forming part of Letters Patent No. 496,908, dated May 9,1893.

Application filed March 25, 1891. Serial No. 386,319. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. SEYMOUR, a citizen of the United'States,residing in the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania, have invented a certain new and useful Improvement inWoven-Wire Fabrics for Mattresses, &c., of which the following is aspecification.

My invention relates particularly to that class of woven wire fabricsconsisting of interwoven parallel rows of spiral coiled wires having atthe edges of the fabric numerous projecting ends of wire which it isdesirable to keep from contact with any material, such as bedding, &c.,with which the wire fabric comes in contact, and my invention is moreespecially applicable to such wire fabric when used as a bed bottom incombination with and supported by coiled spiral springs as shown anddescribed in my United States Letters Patent No. 410,937, of September18, 1889. Heretofore in making such woven wire fabric it has been foundnecessary to finish the edges of the fabric which run at right angles tothe ends of the wires by turning these ends over rods or by bending theends underneath or within the fabric. Such forms are objectionablebecause there is a tendency of the ends of the wire to become loose andto project and tear surrounding material.

The object of my invention is more efiectually to prevent the ends ofthe wire from coming in contact with the surrounding material. Iaccomplish this result by forming the otherwise free and projecting endsof the wire into loops, preferably by twisting together the ends of eachsuccessive pair of projecting wires, and then interweaving with theloops thus formed, a Woven wire binding or border, preferably formed ofone or more Woven coiled wire cables running transversely to the ends ofthe wires, which form the body of the fabric. By this construction theends of the wires forming the body of the fabric do not project beyondthe edge of the complete fabric and are protected by the said binding orborder from coming in contact with the bedding.

Reference now being had to the accompanying drawings: Figure 1 is a planview of a woven wire mattress embodying'my said 1nvention in itspreferred form. Fig. 2 1s a plan view upon a larger scale of a fragmentof the woven structure shown in Fig. 1. F1g. 3 is an elevation of thetransverse section of the structure shown in Fig. 2; wherein plane ofsection is indicated by line X-X.

In the figures A represents the woven wire fabric; wwww represent thestrands thereof, the ends of each successive pa1r be; ing twistedtogether into twisted ends w w w 10 thus forming loops Z.

0 represents the auxiliary binding or border; ss ss represent thestrands thereof.

What'l claim is- 1. Alength of woven wire fabric, formed of a series ofparallel wire" coils intercoiled together and connected in pairs, ateach end, by spirally twisting together, the free ends of adjacentsuccessive pairs, of the parallel wire coils, thereby forming at eachend of the fabric a transverse row of loops having rough ends projectingbeyond said loops, and having a transverse wire coil extending across ateach end of the fabric, united thereto, by having its spiralsintercoiled through its corresponding row of aforesaid end loops, andjointly thereby caging at each end of the fabric, the rough projectingends of the transverse rows of end loops at or near the axial lines ofthe transverse inclosing coils; substantially as and for the purposespecified.

2. A length of woven wire fabric formed of a series of parallel wirecoils intercoiled together, and connected in pairs at each end byspirally twisting together the free ends of adjacent successive pairs ofthe parallel wire coils thereby forming at each end of the fabric,atransverse row of loops having rough ends projecting beyond said loops,and having atransverse wire coil, extending across at each end of thefabric, united thereto by having its spirals intercoiled through itscorresponding row of aforesaid end loops and jointly thereby caging ateach end of the fabric, the rough projecting ends of the transverse rowsof end loops, at or near, the axial 'lines of the transverse inclosingcoils, the

said parts being combined with each other, and with one or moreadditional wire coils, extending across the fabric at each end and theWhole inclosed by the auxiliary or border coil, having its spiralsintercoiled with those of the transverse marginal coils, substantiallyas and for the purpose specified.

WILLIAM S. SEYMOUR.
